... can be used to represent unknown number of parameters passed into a
function.
For example, I write a function g. g calls another function f1.
For example f1 could be different random number generation function.
when f1=rnorm(), it has 3 parameters n, mean and standard deviation.
when f1=rexp(), it has 2 parameters n and rate.
g can be defined as
g <- function(f1, ...) {
f1(...)
}
My problem is what about g calls two functions with unknown number of
parameters.
In this case one ... doesn't help.
If I define g as follows:
g <- function(f1, f2, ...) {
f1(...)+f2(...)
}
It seems ... is only passed to f1, it can't be passed to f2.
Can anybody help me? Thanks!
